Question

It cost David $212 to make chocolate bars this month at least how many chocolate bars must his sell at eight dollars each in order to make a profit

Answer 1

x = numbers of chocolate bars sell

y = 8x

It cost David $212 to make chocolate bars

Profit:

8x > 212

x > 26.5

David needs to sell at least 27 bars to make a profit.

Answer 2

So we take 212/8 to get the number of chocolate bars and we get 26.5. David can not sell half a chocolate bar so he must sell 27 chocolate bars.
